3D imaging provides the ability to view all anatomical structures of the head from any angle without sacrificing clarity. Moreover, 3D imaging is the best way to determine the position of the tooth roots in the bone. Traditional 2D imaging, especially panoramic imaging (a radiograph of all the teeth), possesses inherent magnification and distortion errors that can result in inconsistent information. Distortion errors with panoramic radiographs vary from one part of the film to the next. In 2D imaging (traditional radiographs), anatomical elements become superimposed upon each other. As a consequence, pathologies, extra teeth, and impacted teeth may go undiagnosed when only 2D imaging is used.
